Colorectal cancer screening is a medical process used to detect early signs of cancer in the colon or rectum. It is recommended for adults, typically starting at age 45, especially for those with risk factors like a family history of the disease. Common screening methods include colonoscopy, fecal occult blood tests, and sigmoidoscopy. Early detection through screening can significantly improve treatment outcomes and survival rates. If abnormalities are found during screening, further tests may be needed to confirm a diagnosis. Regular screening is essential for maintaining digestive health and preventing colorectal cancer.
